ABSTRACT:
A chattering prevention circuit includes a counter, which upon receiving an input signal including a chattering signal such as from a switch contact, begins to count a clock signal. When the count reaches a predetermined value, a gate signal is generated which, in turn, is employed to gate the input signal. The input signal is delayed by a time corresponding to the period during which the chattering phenomenon remains in effect following the closing of the contact, thereby to prevent chattering.
